PROBLEM TO BE SOLVED: To restrain vibration while securing safety even on a narrow support projection surface by miniaturization by arrangement of a support position concerning a comparatively small reciprocating piston to be used for a house- hold refrigerator, etc. SOLUTION: An elastic support material 15 is arranged on one end on the side where an overweighed part of a block 5 from a central line CL in the sliding direction of a piston 8 exists and an elastic support material is also arranged on another end roughly symmetrically and, furthermore, another elastic support material is arranged on an extension in the sliding direction of the piston 8 on a bracket 13 on the side of a cylinder 6 against a central line C4 of a crankshaft 4. Additionally, as an elastic support material is arranged and constituted by being biased to the side where the overweighed part of the block 5 exists from the central line CL in the sliding direction of the piston 8 on the bracket on the side of the cylinder 6 opposite to the crankshaft 4, it is possible to restrain vibration while securing safety even on a narrow support projection surface. |
